(English Abstract)
In synchronous secure communications, a synchronization signal is transmitted over the same channel where ciphertext is transmitted for cryptographic synchronization between an encryptor and a decryptor, so, it causes data rate lowering and transmission delay for plain communication. Especially, in poor environments such as wireless channels and so on, since secure communications require a periodic resynchronization protocol, synchronization signal transmission method can dominate its quality. In this paper, we proposed a new synchronization signal transmission method without additional bandwidth as well as resynchronization protocol based on it. We embeded a synchronization signal as a watermark in a transmission image and restored it from a detected watermark in the decryptor. Experimental results of image have demonstrated that the proposed synchronization signal transmission method using watermarking is efficient in transmission rate and can support reliable synchronization detection.
